MACHINE FOR LAYING AND ROLLING QUARTER LININGS.

Application led Marchl 18, 1922. SerialI No. 544,951.v

To all whom t may concern: p

Be it known that I, Ci-rns'rin HUNT, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Laying andl Rolling Quarter Linings, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to a device for use in the manufacture of vulcanized footwear and is herein illustrated as embodied in a device for holding the partially assembled upper of an arctic overshoe during the laying of the quarter lining and for pressing the laid lining into place. Y

In the manufacture of arctic overshoes, commonly called arctics, it is customary .to build the upper complete 0E the last and then to assemble it together with an insole upon a last and proceed to complete its manufacture. In order to promote brevity and clearness, certain steps in the manufacture of a high arctic such as a fourbuckle arctic will be considered. In the manufacture of a high varctic the parts of the upper except the quarter lining are put together and rolled or otherwise pressed to force the parts into firm adhesion. Then the upper, thus far made, is closed by sewing together the rear edges of the quarters. The incomplete upper, wrong side out, is then placed over a form having the general shape of the rear portion of a last, the incomplete upper being so placed upon the form that the back seam is uppermost and the unlined quarters exposed. The quarter lining is now laid on the inside surface of the quarters and rolled. The form hitherto used has been a solid wooden member andthe rolling has been done by a single hand roller.

Under these conditions, the laying of the lining has been accomplished with difficulty by reason of the fact that the operator must use one hand most of the time to hold the upper in proper position upon the form whereas it is very desirable that the operator have both hands free to manipulate the lining. And with regard to the rolling of the lining, this has involved difliculty for the same general reason namely that no means was provided forholding the upperl upon the form, and for the further reason that hand rolling is an extremely laborious operation.

According to one` feature of the invention, means are provided for holding the upper firmly in place. The illustrative device comprises a properly shaped horn and a movable member adapted to draw the rear portion of the upper about the horn and hold the upper rmly in place. This leaves both hands of the operator free to lay the lining and greatly facilitates this operation.

According to another feature ofthe invention, pressing means are provided which may be operated4 after the lining has 'been laid in place. In the illustrative device a series o-f spring-pressed rollers arranged in a circular pattern are mounted in a carrier which may be moved back 'and forth-to cause the rollers to traverse that portion of the upper which is supported on the horn. With this construction, the rolling operation is made .much easier and much more effective.Y e

Referring now to the accompanyingldrawings: v

Figurey 1 is a side elevation, with certain parts shown in section, of a.. machine .in which the present invention is embodied; and e Figure 2 is anend elevation.

Bolted to a bench or table 3 is a plate 5 having rising therefrom a standard 7; and bolted at one end to the standard is a horn 9 which overhangs the table. This horn is designed to support the rear portion of a closed upper; and its operative surface has the general shape of the rear portion of a last. The horn carries on its inner e wall near one end thereof a guide 11 in the form of va U-shaped member, the base of the U being vertical. Slidably mounted on the base of the U is an eye 13 carried by a movable member 15. Extending through bores in the lower ends of armsl 17 which are bolted to and depend from the `upper wall of the horn 9 is a rod 19 attached at one end by a tension spring 21 to one end of the horn and atfthe other by a .cord 23 to a treadle 25, the cord passing over pulleys 27 journaled in the standard 7. Fast to the rod 19 are two sleeves 29, and. pivoted to these sleeves are the'u per ends of links 31, the lower endsof the inks bein pivoted to brackets which are Ybolted to t e movable member 15,l With this construction, when ltionary upright 37.. Alfter the device has horn. The treadle is then depressed, whereupon thefmember 15 is movedv downwardly away from the hornv thereby engaging the front portion of the upper and drawing the rear portion thereof) smoothly aboutl the horn. In, order to, permit` the operator to maintain the upper thus held'vwi-thout keeping his foot on the treadle, thev treadle. is provided with a pawl 35 which. projects yitrOlL the side of the, treadle and may be caused to engage oneor another ofV notches cut in the adjoining side of a smallv stabeen expanded. and locked in expanded oonditionwith the rear portion of the upper drawn smoothly about tholiornathe onorator lays the. quarter lining` in' proper: po-

It is necessary that the lining be pressed firmly against the quarter of the-upper. so as to expel any entrapped air and.. tobring the parts into lirm adhesion, it being understood. that that. Surface of the lining which is next to the quarter is tacky by reason of the presence of unvulcanized rubber, and that if. any air remains entrapped'. between the parts, it will cause blisters in thezsubsequent vulcanizing operation. In order to press the lining: against the quarter of the upper forvthe purposes indicated above, the following construction is provided.

Fast to the tablev 3 at .each sideoi" the horn 9 are guides 39 to receive. rolls 4l, said rol-ls being rotatably mounted at theL lower portion of a circular carrier 43. This carrier is provided with av circular; guideway on its inner facein which is mounted a circular frame 45havingattached to it two handles 47. Mounted on. the frame 45 in spaced rela-tion. andalternately on one side and on the other are a seriesotpressers inthe for-m ofV rollers. 49. Each roller is rotatably mounted in the arms of a fork 51. the stem of whichy extends. through a bor@ in a bOSs on`4 the, frame 45. comp1,-essiony spring. 55

surrounds each. stem 53. as shown; and on Ato the. outer end ofv each stem. is threaded an adjjusting nut 5,7 which determinesthe non malposition offeachroller. Normally, that is;when,the carrier loccupies its inoperative poStorl,l as' shown iny the, figures,- the rollers are arranged irA a f substantially ofi-rcularv pattern. As. soon, however, as. the operator-hw grasped. the' handles 47 and pulled the carrier forward so as to cause the rollerstoV run over the upper upon the horn 9', the pattern of' the rollers changes to conform to the transverse curvature of the horn at the particular' locality .engaged at any moment by the, rollers.v Arnd at any time the operator may rotate the frame 45 in oney direction or the other to bring some one or more of the rollers into contact with any locality which the operator sees is not being properly rolled. In order that, when thecarrier 43 isp'u'lled tothe left as viewed in `Figure l, the rollers may ride upon-the horn without difficulty the' edge ofthe standard 'Z'isbeveled upwardly as indicated at 59.

Although the invention' has-been set forth as embodied in a particular machine, it shouldY be understood that the invention is not, limitedy in the scope of its application to the particular machine which has been shown and described.
